Abstract

We analyse the constraints of the general two Higgs doublet models by evolving the Yukawa coupling constants to high energy under renormalization group. We consider the appearance of a Landau pole or large off-diagonal Yukawa couplings which cause tree level flavour changing neutral currents. Our study shows the latter condition can be used to answer how much Z ₂ symmetry breaking can be allowed in a given 2HDM model.
